ANRITSU CO.
Anritsu Co. introduced the MS8606A digital mobile radio transmitter tester that performs Code Division Multiple Access measurements in less than two seconds. Covering the 300 kHz to 3 GHz frequency range, the MS8606A combines a transmitter tester, spectrum analyzer, power meter and software to analyze signals in CDMA systems. The MS8606A uses an asynchronous mode, allowing it to make measurements using one antenna port connection. It also has an external trigger mode and short code search mode. The menu-driven instrument can take waveform quality measurements in any mode and can measure frequency, timing error, code domain power, transmitter power, occupied bandwidth and spurious emission.

Moffet, Larson & Johnson Inc.
Moffet, Larson & Johnson Inc. announced the availability of its enhanced in-building test transmitter, Sparrow, which is manufactured by Chesapeake Microwave Technologies Inc. The portable transmitter is programmed using a detachable handheld terminal that plugs into the radio-frequency module, and is programmable over personal communications services spectrum. Sparrow generates a clean CW output signal up to 1 watt. The transmitter includes an AC adapter. It will provide seven to nine hours of RF output at full power using optional rechargeable batteries. (703) 741-3500.
Johnson Data Telemetry Corp.
Johnson Data Telemetry Corp. added the JSLM wireless radios in UHF and VHF frequency bands to its fixed data product line. The JSLM radios are designed for half-channel operation with improved radio-frequency specifications for applications worldwide. The JSLM radios are the first offering in JDT’s new line of RNet-style products designed in conjunction with its parent company, Dataradio Inc. (612) 890-8155.
Marconi Instruments Inc.
Marconi Instruments Inc. introduced the 2026Q, an enhanced multisource signal generator designed as a fully integrated radio signal receiver for Code Division Multiple Access cellular and personal communications services handsets. The 2026Q eliminates the need for mechanical radio-frequency switching and additional RF combining or signal conditioning with its two calibrated RF output sources. This allows the
CDMA receiver to be tested for sensitivity in the presence of dual-tone interference and for successful hand-offs between radio channels and between cellular, digital cellular system and PCS bands. The 2026Q can be used at an output frequency range from 800 MHz to 2 GHz, at a combined RF output range of -127 dBm to -13 dBm. (800) 233-2955.
Citel Inc.
Citel Inc. introduced a line of coaxial surge protectors for microwaves, radios, antennas and global positioning and satellite systems that provides protection against lightning surges and electrical transients. The suppressors use a gas tube technology compatible with broadband applications. P8AX coaxial protectors are available for any power from 1 watt to 1,000 watts, and any frequency from DC up to 10 GHz. The protector can be installed as a cable assembly or through the chassis of the equipment to be protected. Grounding can be done either through an external ground screw or a bulkhead mount. (800) 248-3548.
